Abstract
The invention relates to a nonwoven fabric which is bonded at selected points by use of a binder containing particles composed of filler material (a phase change material, among others) and which is not bonded at other selected points. The nonwoven fabric is characterized by a soft touch and good flexibility, and may be used as an interlining material or an intermediate layer.
Claims18
Elastic nonwoven fabric containing crimped fibers and/or crimped filaments including bicomponent fibers or filaments and homopolymer fibers or filaments and optionally uncrimped fibers and/or optionally uncrimped filaments, and wherein said bicomponent fibers or filaments are comprised of polymer components having similar melting points which bicomponent fibers do not provide bonding which is bonded at selected points by use of a binder containing particles composed of filler material, and which is not bonded at other selected points, wherein the weight ratio of the fibers or filaments to the binder and filler material is 50:50 to 30:70.
